Applcation filed September 23, 1912. Serial No. 721,988.

To all whom it may concern: Be it known that I, ROMEO WILLIAMSON, acitizen of the United States, and resident of Milwaukee, in the countyof Milwaukee and State of WVisconsin, have invented certain new anduseful Improvements in Machines for Forming Hollow Glassware; and I dohereby declare that the following is a full, clear, and exactdescription thereof.

My invention has for its Object to provide a simple, economical andeife'ctive machine for the manufacture of'pari'sons to be uti-l lized informing various hollow glass arti 'clesYthe' particular object of saidinvention glass, the hopper being being to provide parisons of uniformarea, whereby the finished articles will be accurate in theirdimensions. v

Specifically my invention has for its object to provide a seriesofshiftable hoppers adapted to be brought under a discharge nozzle of astorage reservoir and when in this position the hop H is adapted toreceive a predetermine v quantity of molten supported by ascalemechanism, which mechanism will automatically cut oil the supply ofmolten glass, whereby a gather of predetermined quantity is depositedtherein, thus insuring measured quantities of molten glass for backparison,

the gather either being extracted from the hopper by suction ordischargedtherefrom gravity into a parlson mold With the above objectsin view the invention consists in certain eculiarities of construotionand combinatlon of parts as set forth hereinafter with reference to theaccompanying drawings, and subsequently claimed.

In the drawings Figure 1 represents a sectional elevation in diagramillustrating a machine embodying the features of my invention, and Fig.2, a detailed sectional plan view of the same, the section beingindicated by line 2 2 of Fig. l.

Referring by characters to the drawings, 1

represents an .endless belt member, into the links of whichare looselymounted a series of hoppers 2 having vented valve-controlled stems 3that extend from their bottoms. As illustrated in Fig. l, the.hopper-carrying mechanism is adapted to travel .the direction indicatedby the arrow and the first hopper A from left to right in said view ispositioned so that upon the next intermittent forward movement of thecarrier mechanism its stem 3 will engage a fixed camplate 4, wherebysaid hopper will be lifted, the cam-plate constituting part of a bracketat. The next hopper B as shown has just traveled over the cam 4t and isat rest upon the foot 5 of a scale lever 5, one arm of which lever isconnected by a link 6 to an air supply valve 7 the link 6 being providedwith a series of scale weights 6', whereby the lever is held. rigidly inthe position shown against a stop-pin 5". In this elevated position thehopper is alined to receive the flow of molten glass from a d1schargenozzle 8 of a reservoir 9, which reservoir constitutes part of a meltingfurnact 7C and forms no part of my invention.

hen the gather in the hopper has arrived at a predetermined weight itisapparent that the foot end of the scale lever 5 will drop, together withthe hopper. Coincident with this movement air is admitted through valve7 by suit-able pipe connections to the front end of a cylinder 10, and,as best shown in Fig. 2, this air pressure acts upon a piston 11, whichpiston is in link connection with shear-plates 12, the fulcrum of thesame being mounted upon a suitable bracket 13 that forms part of thecylinder, it being understood that the cylinder is also suitablysupported by a standard 14:. The shear-plates, as shown are slightlybeveled toward each other and the stream of molten glass is adapted totravel by gravity therebetween. When the air pressure is admitted to theforward end of the cylinder, the said blades are drawn together by theirconnection with the piston 11, thus cut-ting oif the supply of glass tothe'hopper therebelow and'as the blades close one upon the other they,together form an inclined trough, whereby the stream of molten glassthat is cut oil from the hopper thereunder is directed into thesucceeding hopper A. The flow of molten glass will then be directshearmembers which now form a trough and as the mouth of the hopper A passesbeyond the discharge ends of the lapped shear-blades, the saidshear-blades start to thus direct a constant stream of glass into saidhop er A, the discharge point of which stream tffereby follows themovement of said hop or A to its point of rest. Hence it will ed intohopper A by the inclined closed open gradually toward their hinge pointto be 0 served that a constant stream of molten 11o lass is nmintained,being cut off from the opper'at rest under the reservoir and de- Co-iniileeted into the succeeding hopper.

eident with this movementand cu -off of disposed in alincn ent with thetravel of the hoppers is a parison mold 15, the members of which arehinged to a hollow arm 16 that is fulcrumed to the standard 14.

Mounted in the hollow arm 16 is a crank 17 that is linked to a channeledplunger 18, which plunger is adapted to enter the mold cavity at apredetermined time to form a blow-hole. The crank'l? also carries anarm17 that engages a cam-plate 17" which projects from the standard. Thechambered portion of the hollow arm 16 communicates with one end of acylinder 19 through a flexible pipe connection 19, the cylinder beingprovided with a reciprocative pistonhead 20. The body opening 15 of thetwopart mold is arranged to be centered over the series of hoppers asthey are shifted into alinement therewith, the said mold being providedwith a shoulderedend 15" that forms a practically air-tight closure forthe mouth of the hopper. Hence it will be seen that as the mold andhopper containing the measured gather of glass are coupled to getherthat the contents of said hopper can readily be sucked into the moldcavity by suction-stroke of the piston 20. Thereafter the mold isshifted to an air -controlled closure-plate 21. This plate is connectedto a piston-head 22 that is mounted in a cylinder 22, which cylinder isadapted to re- "When the mold is' ceive air at its ends.- brought into'alinement with the closureplate air is admitted to the outer end of thecylinder, whereby said closure-plate is securely chucked against thebottom or body end of the mold to thus shield the same. In shifting themold to the closure-plate move ment of the crank will cause the plungerto enter the neck of the parison and thus form a blow-hole therein.Thereafter the piston 20 is moved forward to thus supply air-pressuresuiiicient to distend the parison by its entrance thereto through theplug 1 whereby said parison is completed, it being understood that themechanism in connec At a predetermined distance from i the dischargenozzle 8 of the reservoir and tion with the parison mold in its specificform forms no part of my invention and is simply diagrammaticallyillustrated to illustrate means for extracting .the measured gathers bysuction from the hoppers in succession and for blowing the parison tocompletion.

Attention is cal ed to the fact that while I do not claim any particularmechanism for finishing the bottle that what I do claim and consider animportant feature of-my invention is that I utilize a vacuum producer orsuction apparatus whereby the gather of glass is drawn up fromthe hopperinto the parison mold the air channel being through a reciprocativemandrel 18 that is retracted entirely from the head end of the moldcavitycoincident to a suction movement. Thus the head cavity of saidmold is entirely filled with the gather of glass. It being furtherunderstood that I may, without departing from the spirit of myinvention, shift the mold thereafter and utilize a solid mandrel forforming a blow-hole in the heretofore uninterrupted upper face of theparison head. i
